Inombolo octane - kusho ukuthini?

Uphethiloli imiqulu ehlukahlukene washisa emhlabeni wonke. izinhlobo zayo eziningi, kodwa thina, njengoba njalo, ngifuna ukuthola umkhiqizo kangcono izinga. Ukuze ukuhlola amamaki ezahlukene fuel usebenzise Inkomba ekhethekile - inombolo octane, okungase njani izakhiwo nophethiloli. Ikakhulukazi le osebenza ku detonation yayo izakhiwo kanye nokwenzeka usebenzisa amamaki ezahlukene esasiphethwe izinjini yesimanje

Ukuze uzwisise ukuthi yini inombolo octane, kubalulekile ukuba sicabangele izinqubo ezenzeka ngesikhathi ukusebenza injini. Lapho uqala nje ukubona, silula - lapho piston ihamba phezulu liyancipha isilinda ivolumu, elise therein fuel ingxube (ingxube emoyeni ngezabelo ezithile nophethiloli umusi) onomfutho. Ikhandlela unika inhlansi ingxube wakhanyiswa nombhangqwana okuholela amandla omlilo, anda kakhulu emqulwini, le piston idluliswa phansi.

Kuchazwe luluhle ngesimo izikimu, kodwa eqinisweni enqubeni zikhona umehluko wemisindo nemiqondo yamagama amaningi ezingaba kakhulu ukushintsha isithombe. Ngaphandle ngokuthinta ubuqili injini, sicabanga kabanzi amandla omlilo uphethiloli. Ngokuvamile kukhona ethule, amandla omlilo bushelelezi. Kwezinye ushintsho kwakhiwa ngesikhathi senqubo. Ziyahlukahluka kokuntengantenga kwezomnotho, futhi lapho abaningi abasuka ezithile omlilo alufakwa singenzeka.

Kuzoba inqubo ehluke ngokuphelele. Izinga ilangabi esiphelweni lapho abavamile omlilo - amashumi amamitha ngomzuzwana, futhi ngesikhathi omlilo kuqhume - kuze kufinyelele 2500 m / s. Kulokhu, injini esebenza ngokweqile umthwalo izinto, kokuba umsindo ongajwayelekile injini engqongqoza. Okunjalo abukhali, ukushaya abashayeli abanolwazi umsindo zinezikhathi elula - "umunwe u-", okuyinto kuvela izimpawu zokuqala detonation futhi kubathinta kabi injini ukusebenza.

Anti-engqongqoza izakhiwo uphethiloli nje ephawula inombolo octane. Manje usungakwazi phindela motor. Iqiniso lokuthi Abaklami zihlale ukhathazeke ngokuthola amandla ngaphezulu kusukela motor efanayo, ceteris paribus. Indlela elula - ukwandisa zlib isilinganiso injini.

Ngokwandisa zlib isilinganiso ingxube ukukhwezelwa inqubo amandla omlilo ukukhishwa amandla, bese kukhula amandla injini. Lapha octane zikaphethiloli ephawula izinhlobo ezahlukene ngokuvumelana propensity yabo detonation. Ayanda ukubaluleka, kancane amathuba engqongqoza. Okuqukethwe kwalo kunqunywa ukuthi kungenzeka hydrocarbon ahlukahlukene kaphethiloli. Ukuze usungule antiknock ukumelana oluvame ukusetshenziswa ngezindlela ezimbili - motor nocwaningo.

Inqubo sokukala isibalo octane esimweni ngasinye ine siqu yayo nokubaluleka kwalo kuyoba ezahlukene ngayinye umbono nesilinganiso. Lo mphumela uboniswa ekubizweni sha uphethiloli. Uphethiloli, wabonakalisa ngezimanga indlela motor ekhethiwe, isib, A-92, futhi ngo-Research - AI-92. Kukhula inani octane, ayanda ukumelana fuel detonation, futhi ibhekwa njengenye nqampuna umhlabeleli.

e ongaphakeme grade uphethiloli ukwandisa ukumelana detonation ungeze okuyinto ukunciphisa ukuthambekela knock - antidetonators, lapho uphethiloli ingasetshenziswa njengoba high-octane. Omunye wabo tetraethyl phambili. Siyabonga kuye nezinye izithasiselo isetshenziswa ngesikhathi esifanayo ne-ke, encishisiwe ikhono detonation ingxube ezivuthayo futhi kwandisa octane. Gasoline lapho ungeza lezi izithasiselo, ngokuthi leaded. Ukuze ukuhlukanisa kusukela evamile, namabala. Okokhelekayo engqongqoza ukumelana uthola umfutho, kodwa lokhu kuthathwa njengesibikezelo esiyiso igesi enobuthi, futhi akukho Kunconywa ukusetshenziswa emazweni amaningi.

Isetshenziswa njengesici fuel kanye negesi. Lapho usebenzisa i-izinkinga detonation musa kuphakama, ngoba inombolo octane gas ngenhla: kuba amayunithi 105 ngokwesilinganiso.

Indaba kusenza siqonde emabangeni ahlukahlukene uphethiloli, ikhwalithi kanye nezici. Incazelo izimbangela detonation kanye nomthelela kwi izakhiwo octane uphethiloli.
